PAUMA VALLEY - An investigation was under way Monday into the death of a 65-year-old man who was struck by a car while laying in the middle of Highway 76 in the Pauma Valley.

Officers and medical personnel were called to eastbound Highway 76, east of Adams Drive, at 7:11 p.m. Sunday, according to California Highway Patrol Officer Jim Bettencourt.

Once there, they learned a 61-year-old Escondido woman driving her 2007 Lexus ES350 about 50 miles per hour struck the man as he lay in the middle of eastbound lanes, Bettencourt said in a statement.

The man lived just east of the scene and the county coroner's office was investigating whether he suffered any medical issues prior to being struck, the officer said. He was pronounced dead at the scene, according to the coroner.

The woman waited at the scene for authorities and was not expected to face any criminal charges, Bettencourt said.
